I measure a 5 wide, which is impossible to find! Sanuk actually carries a 5! I own 3 different styles of Sanuk. Even though it is not technically a wide, it is wide enough, with the soft fabric. I also have a high instep, but the top of the shoe accommodates that. These are one of the most comfortable shoes I own. The only con (which only happened after I wore them for about 6 months), is that they can get a little stinky. But, that's probably just me! I don't wear them with socks and I do tend to have stinkier feet that most…ha ha ha! Thank you Sanuk for realizing that some of us do have small feet!
